Answer:
Hydrogen has only 1 valence electron in its outermost shell.
Explanation:
Answer:
CoSO4.7H2O
Cobalt II tetraoxosulphate VI heptahydrate
Explanation:
According to IUPAC nomenclature, compounds are named systematically.
We were told that there are seven water molecules in each formula unit Hence the correct formula of the compound is CoSO4.7H2O
According to IUPAC system, the metal is first named, followed by its oxidation state in Roman numerals. Then the name of the anion is mentioned as well as the number of water molecules. We have to take into account the correct prefix signifying the number of molecules of water of crystallization.
Calcium & Barium. Elements that share same/similar properties lay on the same group/family on the periodic table!
One.
In organic chemistry, an electrophile<span> is a reagent attracted to electrons.</span>Electrophiles<span> are positively charged or neutral species having vacant orbitals that are attracted to an electron rich centre. It participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile.

Carbon attached to O is electrophylic.
Answer:

Explanation:
Hello!
In this case, since it is possible to assume that the heat released by the reaction is absorbed by the water in the calorimeter we can write:

Now, since the reaction between silver nitrate and hydrochloric acid is:

We can see there is a reacting 1:1 mole ratio, thus, the reacting moles are computed via the molarity of the solutions:

Finally, the enthalpy of reaction is:

And in kJ:
